FIELD

The present application relates to the field of information processingtechnology, and in particular to a desktop generation and operationmethods for a mobile terminal and corresponding devices thereof.

BACKGROUND

With the development of communication technology, the mobile terminal isincreasingly popular, and there are more and more application programswhich can be run on the mobile terminal. In order to open theseapplication programs, it needs to find an executable file of theapplication program on the mobile terminal and then click the executablefile to start the application program to run. Usually, in order to startthe application program conveniently, a shortcut for the applicationprogram is generated on a desktop of the mobile terminal once theapplication program is installed on the mobile terminal. The shortcutincludes contents indicating the application program, for example, anicon or a program name. The number of shortcuts on the desktop increasesas more application programs run on the mobile terminal. These shortcutseach occupy a predetermined region of the whole desktop and are arrangedon the desktop based on a preset rule (for example, arranged close tothe right side and the upper side of the screen of the mobile terminal).In order to facilitate management of the shortcuts of applicationprograms, it is required in the conventional technology that eachshortcut icon on the desktop is rounded rectangular. During practiceprocess, the shortcut icons of application programs have various shapes,for example, a regular shape such as a triangle or a circle, or anirregular shape. Before these icons with different shapes are presentedon the desktop of the mobile terminal, the shortcut icons are generallymanufactured to be in a shape of rounded rectangle by using a specialsoftware, such that the shortcut icons are arranged on the desktop ofthe mobile terminal smoothly. However, this way limits presentationforms of the shortcut icons of application programs, reduces thetolerance of the mobile terminal to application programs, and increasesthe difficulty in presenting the shortcut icons on the desktop.

DETAILED DESCRIPTION

In order to better understand the technical solutions of the applicationby those skilled in the art, hereinafter the technical solutions of theembodiments of the application are described clearly and completely inconjunction with the drawings of the embodiments of the application.Apparently, the described embodiments are only some of embodiments ofthe application, but not all embodiments. Any other embodiments obtainedbased on the embodiments of the application by those skilled in the artwithout any creative work fall within the scope of protection of theapplication.

Some concepts related to the application are briefly explained beforedetailed description of various embodiments of the application. The“desktop” mentioned in the application refers to a space for presentingan icon and/or program name by an operating system. The “icon” mentionedin the application refers to a shortcut on the desktop indicating thatthere is an application program. A user can open a target applicationprogram associated with an icon by clicking the icon. In theconventional operating system, the overall shape of the icon isgenerally rounded rectangle. The “standard mode” mentioned in theapplication refers to a single-desktop mode, i.e., there is only onedesktop in the screen of the mobile terminal. The “multiple-desktopmode” mentioned in the application refers to a case that there aremultiple desktops in the screen of the mobile terminal.

Reference is made to FIG. 1, which illustrates a flow of a desktopgeneration method for a mobile terminal according to an embodiment ofthe application. The embodiment includes following steps S101 to S103.

In step S101, a block class object is created, where the block classobject includes attribute information.

A block class object needs to be created in order to generate a block onthe desktop and the block class object is created by performinginformation interaction with the operating system of the mobileterminal. The block class object includes multiple attributes. Forexample, the block class object may include a background attribute (forrepresenting the background color of the block), a shape attribute (forrepresenting the overall shape of the block), a size attribute (forrepresenting a distance of the block in a certain direction, forexample, the size attribute of a round block may be a radius R of thecircle, and the size attribute of a rectangular block may be a width[width] or a height [height]), a position attribute (for representingcoordinates of the block on the desktop [x, y, z]), and a colorattribute (color [r, g, b, a] for representing the overall color of theblock), and may further include attributes such as alpha, visible andscale. In creating the block class object, certain attributes may beselected based on actual requirement to describe the block class object.

In step S102, multiple blocks are drawn by calling a drawing functionbased on the attribute information of the block class object, to makethe multiple blocks be distributed on a whole screen of the mobileterminal without overlap to form a desktop.

After the block class object is created, blocks are drawn by calling adrawing function based on attributes of the block class object. Thenumber of blocks required to be drawn depends on factors such as theshape of the block, the size of the block and the size of the screen ofthe mobile terminal. During actual application, after the shape of theblock, the size of each block and the size of the screen of the mobileterminal are determined, the number of blocks required to be drawn andthe position for drawing each block are calculated. The shape of theblock, the size of each block and the size of the screen of the mobileterminal are not limited, as long as these blocks can be distributed onthe whole screen of the mobile terminal without overlap to form adesktop. Here the drawing function refers to a tool for drawing in abroad sense based on parameter information in response to aninstruction. The drawing function has different names in differentprogramming languages. For example, the drawing function is referred toas draw function in C language, and is referred to as draw method injava language. In the embodiment, the tool and the language system ofthe tool are not limited, as long as the corresponding blocks can bedrawn based on the attribute information of the block class object.

In step S103, a shortcut icon and/or program name of a shortcut for anapplication program is presented in an idle block on the desktop, in acase that the shortcut for the application program is required to bepresented on the desktop. The idle block is a block on which no shortcutfor an application program is presented.

In general, once a desktop consisting of multiple blocks is formed onthe screen of the mobile terminal, the process of desktop generation isfinished. However, the desktop generation is not only for generating adesktop and the desktop is used to display icons of applicationprograms. Hence, in practice, the desktop in the application is adesktop on which there are at least one block presenting an icon of anapplication program. Based on this, in the embodiment of theapplication, after the desktop is generated in the above step, an idleblock is searched for from the multiple blocks in the desktop if ashortcut for an application program is required to be presented on thedesktop, and then the icon of the application program is presented inthe idle block. Here “an icon of the application program being requiredto be presented on the desktop” may refer to “requirement” generated invarious trigger conditions. For example, an application program isrequired to be registered in the operating system during or after theapplication program is installed on the mobile terminal; the operatingsystem generates a message after learning that certain applicationprogram is registered, and a monitor may be provided to monitor thenotification message transmitted from the operating system in theembodiment of the application; and if the notification message ismonitored, it is considered that the requirement for “creating ashortcut for the application program on the desktop” is generated. Underthe trigger of such requirement, an icon for the application programprepared in advance, for presenting the shortcut for the applicationprogram, is read. Before, during or after the icon is read, whetherthere is an idle block on the desktop is detected; if there is at leastone idle block, one idle block is selected from the at least one idleblock to present the shortcut icon of the application program. The idleblock may be selected randomly or based on a preset rule. For example,an idle block close to the left side and upper side of the screen of themobile terminal is selected. Here the idle block is a block on which noshortcut for an application program is presented. During actualapplication, a list may be set in the background of the operating systemof the mobile terminal for recording the sequence number and position ofeach block on the desktop and whether a shortcut icon is on the block,in the application. Once a shortcut icon is presented on one block bywriting, this event is registered in the list, and in this way it can beconveniently known which blocks are idle by making a query on the list.It is to be noted that, for convenience of description, the aboveclarification is made by taking an example that only the shortcut iconof the shortcut for the application program is presented on the block,practically it may also be that only the program name or other relatedinformation of the application program is presented on the block. Inactual application, both the shortcut icon and program name of theapplication program are presented in most cases.

According to the solution of the embodiment, the block class objectincluding attribute information is created firstly, then multiple blocksare drawn by calling a drawing function based on the attributeinformation of the block class object to make the multiple blocks bedistributed on the whole screen of the mobile terminal without overlapto form a desktop; in a case that a shortcut for an application programis required to be presented on the desktop, the shortcut is presented inan idle block on the desktop. Compared with the conventional technology,blocks are created and the desktop of the mobile terminal is formed byarrangement of these independent blocks in the embodiment of theapplication. If a shortcut for an application program is required to bepresented on the desktop, the icon or program name of the shortcut ispresented in one block rather than on the whole desktop (occupyingcertain region of the whole desktop), i.e., the icon or program name ofthe application program is presented using the block instead of thewhole desktop. Therefore, the icon or program name of the applicationprogram can be in various shapes, and thereby increasing the toleranceof desktop to the application program and reducing the difficulty inpresenting the shortcut icon on the desktop.

In order to illustrate the above technical effect more clearly,clarification is made in conjunction with FIG. 2 hereinafter. FIG. 2illustrates a conventional desktop form and a desktop form of theembodiment. FIG. 2(a) illustrates a conventional desktop form. Thedesktop is presented as a whole panel, the shortcut icon and programname of each application program occupy one rounded rectangle region,and shortcut icons and program names of these “rounded rectangles” arearranged on the whole panel. FIG. 2(b) illustrates a desktop form of theembodiment. The desktop includes multiple blocks independent of eachother, and on each block a shortcut icon and program name of anapplication program are presented. The shortcut icon may be in a regularshape, for example, application program 4 (triangle) and applicationprogram 9 (circle) as shown in FIG. 2(b), or may be in an irregularshape, for example, icons of application program 2, application program8 and application program 11 as shown in FIG. 2(b). It can be seen that,blocks exist on the desktop independently, and the shortcut icons on theblocks are not limited to the shapes of the shortcut icons of theapplication programs, thereby the tolerance of the desktop to theapplication program is increased and the shortcut icon needs not to bemanufactured specially by the user in advance.

In the above embodiments of the application, the shapes of the blocksand the number of the blocks on the desktop are not limited, and theobject of the application can be realized as long as blocks drawn usingthe drawing function can be distributed on the whole screen of themobile terminal. However, in practice, it is preferred in theapplication that blocks on the desktop are rectangular blocks and theblocks are arranged in a “matrix”, i.e., presenting N×M blocks (referredto as PanelNM) on the screen of the mobile terminal, where N is thenumber of blocks on the desktop of the mobile terminal in a transversedirection, M is the number of blocks on the mobile terminal in alongitudinal direction, and N and M each are natural numbers greaterthan or equal to 2. The (N×M) blocks form a desktop. For example,reference is made to FIG. 3, which illustrates a (3×3) desktop (referredto as Pane 19). It can be seen from FIG. 3 that: there are 3 triangularblocks in the transverse direction and 3 triangular blocks in thelongitudinal direction on the desktop, and there are 9 triangular blocksin total. Based on the similar principle and in the similar manner, adesktop of (6×6) Panel 36 or a desktop of (9×9) Panel 81 can be formedon the screen of the mobile terminal based on actual requirement. Inaddition, in order to view conveniently and detect a triggered regionaccurately, preferably an interval of certain distance is set betweenevery two adjacent blocks in the application. The size of the intervalmay be set according to actual application requirement, for example, 2mm. By increasing the interval between adjacent blocks, in one aspect,the layout of the blocks on the desktop is more explicit and morespiritual, which is convenient to view and improves user experience, andin another aspect, trigger regions (in a touch screen, a region whereeach block is located is a trigger region) of different blocks aredistinguished apparently, and it is beneficial to detect triggerinformation accurately, thereby operating correctly.

After the desktop consisting of multiple blocks (a block on which ashortcut icon and a program name of an application program are presentedis referred to as a non-idle block; and a blank block is referred to asan idle block) is generated on the mobile terminal as described above, adesktop user may perform various operations on the desktop. For example,the desktop user may perform a click-to-open operation on theapplication program. Association between the non-idle block and theshortcut icon of the application program is established. In the casethat the desktop is a touch screen, the desktop user clicks a certainblock with a finger and this trigger event is detected by the block,then an address of an executable file of a target application program isfound out based on the association between the block and the shortcuticon and running of the executable file is started, thereby theapplication program is opened. For another example, the desktop user mayperform selecting and moving operation on the application program. Oncethe desktop user selects a block by a gesture, the desktop user holdsdown and moves the block to drag the block to a target position. Inaddition, operations such as deleting a block and page turning of thedesktop may also be performed. The page turning of the desktop may beperformed in two ways. One way is that, only one desktop consisting ofblocks is generated, and the second desktop is then generated accordingto the preceding steps in response to a trigger. For example, in thecase that the user touches the touch screen and slides the desktop leftand right by using a finger, a new desktop including multiple blocks isgenerated in the new region line out according to the steps in the aboveembodiments, thereby page turning is achieved. The other way is that,multiple desktops are generated once, only one desktop is displayed onthe screen of the mobile terminal, and the block containing the shortcuticon and the program name which is not presented in the current desktopis presented in response to a trigger. For example, in the case that thenumber of shortcut icons and program names of application programsrequired to be presented on the desktop is greater than the number ofblocks of one screen, the relationship between the blocks and theshortcut icons and program names of application programs out of the onescreen is recorded, and the blocks which are not presented on thecurrent screen are presented in sequence (or according to other rules)when the user slides on the desktop, thereby page turning is achieved.

The contents described above are technical solutions of the applicationfor a standard desktop mode (i.e., there is only one desktop on thescreen of the mobile terminal), and hereinafter the technical solutionsof the application will be further illustrated for a multiple-desktopmode (i.e., there are multiple desktops on the screen of the mobileterminal). Reference is made to FIG. 4, which illustrates a desktopoperation method for a mobile terminal according to an embodiment. Theembodiment includes following steps 5401 to S402.

In step S401, an action is performed in a predetermined action manner topresent multiple desktops according to any one of claims 1 to 3 on ascreen of the mobile terminal.

A desktop user may change the presentation way of the desktop on themobile terminal in a predetermined action manner, to achieve conversionbetween different desktop modes. For example, in the case that thecurrent desktop is in a standard desktop mode, the desktop user performsa grip action on the desktop consisting of multiple blocks in thestandard desktop mode and then multiple desktops are presented on thescreen of the mobile terminal; these desktops may be desktops generatednewly under the trigger of the “grip” action or may be multiple desktopsgenerated when the desktop in the standard desktop mode is generated andpresented simultaneously under the trigger of the “grip” action.Similarly, in the case that the current desktop is in themultiple-desktop mode, the desktop user spaces out two desktops in themultiple-desktop mode with figures, and the desktop is returned to thedesktop state in the standard desktop mode. In addition to be triggeredby a special gesture set in advance, the conversion between the twomodes may also be triggered by a conversion button. Once the button istriggered, the current desktop mode is conversed to other desktop modedifferent from the current desktop mode. The embodiment refers to anoperation method in the multiple-desktop mode.

In step S402, an operation message is received by taking the desktop orthe block included in the desktop as an operation object, and acorresponding operation is performed on the operation object based onthe type of the operation message.

In the case that multiple desktops are presented on the desktop of themobile terminal, an operation message may be received, a desktop or oneor more blocks included in a desktop in the multiple-desktop mode istaken as an operation object, and a corresponding operation is performedon the operation object based on the type of the operation message.Different types of operation messages may correspond to differentoperation objects, and accordingly may correspond to differentoperations. In order to describe the operation on the desktop of themobile terminal in the embodiment more clearly, three operation ways,i.e., integral movement of the desktop, multi-selecting and moving ofblocks in the desktop, and displaying and hiding of the desktop, aredescribed hereinafter.

The first operation way is integral movement of the desktop. In thisoperation way, the desktop including multiple blocks is as the operationobject, and the type of the operation message is integral movement ofthe desktop. In the multiple-desktop mode, multiple Panel (NM), forexample, 4 or 9 Panel9, are displayed on the screen of the mobileterminal. Here for convenience of description, a predetermined gesturefor indicating integral movement of the desktop is set as “holding downand dragging” the desktop. In the application, an independent detectormay be provided for each desktop, or one detector is shared by all thedesktops, for detecting whether an operation message of integralmovement is received by one of the multiple desktops. For example, thedetector detects that there is a trigger message of “holding down” for acertain desktop (referred to as desktop A), then it is considered thatthe message of integral movement of the desktop A is received; in thiscase, a list corresponding to the desktop A is created for recordingsequence numbers of blocks included in the desktop A and positioninformation of the blocks in the desktop A in the application. Further,a target position to which the desktop A is to be moved integrally isdetected. For example, the detector detects that the “holding down”stays at a certain desktop position, then it is considered that thestayed position is the target position; in this case, the desktop isdrawn at the target position by calling a drawing function, based on thesequence numbers of the blocks and the position information of blocks inthe desktop recorded in the list. During actual application, the targetposition to which the desktop A is moved may be a position where anotherdesktop (referred to as desktop B) is located. In this case, in order toavoid the desktop B being covered, sequence numbers of blocks in thedesktop B and position information of the blocks in the desktop B may berecorded in a list, and the desktop B is drawn at the position where thedesktop A is located by calling the drawing function, based on thesequence numbers of the blocks in the desktop B and the positioninformation of the blocks in the desktop B recorded in the list. In theconventional multiple-desktop mode, the shortcut icon of eachapplication program is presented on a whole desktop, which can not bemoved integrally, therefore, there is no practical meaning for themultiple-desktop mode. However, in the operation way of the embodiment,in a case that the desktop includes 9 blocks originally, the 9 blocksfunction as one big block to move, i.e., are moved integrally.

The second operation way is multi-selecting and moving of blocks in thedesktop. In this operation way, the block in the desktop is as theoperation object, and the type of the operation message is selectingblocks in one or more desktops and moving the selected blocks to atarget desktop. Here for convenience of description, a predeterminedgesture for indicating multi-selecting and moving of blocks in thedesktop is set as “clicking, holding down and dragging” the blocks inthe desktop. In the multiple-desktop mode, each desktop includesmultiple blocks. The detector may detect whether an operation message ofselecting and moving is received by the block in the screen of themobile terminal. For example, the detector detects that several blocksare clicked, then it is considered that these blocks receive theoperation message of selecting and moving; in this case, sequencenumbers of the clicked blocks and position information of the clickedblocks in the desktop are recorded in a list. The list is created whenthe first of the clicked blocks is clicked. In order to obtain a goodvisual experience of the desktop user, once the desktop user holds downone of the clicked blocks after the clicking operation ends, otherclicked blocks may be set to be converged around the “held down” block.These clicked blocks may be from the same desktop or different desktopsin the multiple-desktop mode. After the desktop user “holds down anddrags” the block to a certain target position, positions of idle blocksand the blocks in the list are interchanged based on sequence numbers ofthe blocks and position information of the blocks in the desktoprecorded in the list, thereby multi-selecting and moving of the blocksis achieved.

It is to be noted that, in some cases, the number of idle blocks in thedesktop where the target position is located may be less than the numberof blocks selected to be moved by the desktop user, i.e., the desktopwhere the target position is located has “insufficient space”, in thiscase positions of the selected blocks and positions of the idle blocksin the desktop where the target position is located are interchanged insequence according to a priority selection, and other extra selectedblocks are returned to the original positions. In actual application, inorder to avoid the case that the blocks selected by the desktop user cannot move to the target position smoothly, it is preferably in theapplication that once the target position to which the blocks are to bemoved is detected, it is detected whether there is an idle block in thedesktop where the target position is located; and if there is an idleblock and the number of the idle blocks is greater than or equal to thenumber of the blocks recorded in the list, i.e., the desktop where thetarget position is located has “sufficient space”, positions of the idleblocks and positions of the blocks in the list are interchanged based onsequence numbers of the blocks and position information of the blocks onthe desktop recorded in the list. In order to improve user experience, agreen block (or corresponding text) may be displayed around the desktopwhere the target position is located in the case of “sufficient space”of the desktop where the target position is located, and a red block (orcorresponding text) is displayed in the case of “insufficient space” ofthe desktop where the target position is located.

The third operation way is displaying and hiding of the desktop. In thisoperation way, the block in the desktop is as the operation object, andthe type of the operation message is displaying and hiding of thedesktop. As described above, the block in the desktop has a visibleattribute, and in the multiple-desktop mode each desktop as a whole mayalso have a visible attribute. Here for convenience of description, apredetermined gesture indicating displaying and hiding of the desktop isset as “double-clicking” the block in the desktop. Hereinafter it isillustrated by taking the desktop Panel 9 as an example. The desktopPanel9 and blocks in the desktop Panel9 each have a visible attribute,and the displaying and hiding states of the Panel9 and its blocks may bechanged by changing the visible attribute. Assuming that the Panel9 isvisible initially, i.e., the value of visible is true, shortcut iconsand program names of application programs presented on blocks in thePanel9 are displayed. Once the desktop user double-clicks, the attributevalue of the visible attribute of the block changes to be the oppositeattribute value, i.e., changing from true to false. The desktop is thenrefreshed, and in this case the block in the desktop drawn by callingthe drawing function is not drawn, thereby hiding the desktop and theblocks in the desktop. Similarly, if the Panel9 is invisible initially,blocks in the desktop are drawn by calling the drawing function based onthe attribute value after the desktop is refreshed, thereby displayingthe desktop and the blocks in the desktop.

The embodiments of the desktop generation method and the desktopoperation method for the mobile terminal of the application aredescribed in detail above, accordingly, a desktop generation apparatusfor a mobile terminal and a desktop operation apparatus for a mobileterminal are further provided according to embodiments of theapplication. Reference is made to FIG. 5, which illustrates a structuralblock diagram of the desktop generation apparatus for the mobileterminal according to an embodiment of the application. The apparatusincludes a class object creating unit 501, a block drawing unit 502 anda shortcut presenting unit 503.

The class object creating unit 501 is configured to create a block classobject, where the block class object includes attribute information.

The block drawing unit 502 is configured to draw multiple blocks bycalling a drawing function based on the attribute information of theblock class object, where the multiple blocks are distributed on a wholescreen of the mobile terminal without overlap to form a desktop.

The shortcut presenting unit 503 is configured to present, in an idleblock on the desktop, a shortcut icon and/or program name of a shortcutfor an application program, in a case that the shortcut for theapplication program is required to be presented on the desktop, wherethe idle block is a block on which no shortcut for an applicationprogram is presented.

A working process of the apparatus is as follows. The class objectcreating unit 501 creates a block class object including attributeinformation. The block drawing unit 502 then draws multiple blocks bycalling a drawing function based on the attribute information of theblock class object, to make the multiple blocks be distributed on awhole screen of the mobile terminal without overlap to form a desktop.The shortcut presenting unit 503 then presents a shortcut icon and/orprogram name of a shortcut for an application program in an idle blockon the desktop in a case that the shortcut for the application programis required to be presented on the desktop, where the idle block is ablock on which no shortcut for an application program is presented.

In the apparatus embodiment, the block class object including attributeinformation is created firstly, then multiple blocks are drawn bycalling a drawing function based on the attribute information of theblock class object, to make the multiple blocks be distributed on thewhole screen of the mobile terminal without overlap to form a desktop;in a case that a shortcut for an application program is required to bepresented on the desktop, the shortcut is presented in an idle block onthe desktop. Compared with the conventional technology, blocks arecreated and the desktop of the mobile terminal is formed by arrangementof these independent blocks in the apparatus embodiment. If a shortcutfor an application program is required to be presented on the desktop,the icon or program name of the shortcut is presented in one blockrather than on the whole desktop (occupying certain region of the wholedesktop), i.e., the icon or program name of the application program ispresented using the block instead of the whole desktop. Therefore, theicon or program name of the application program can be in variousshapes, and thereby increasing the tolerance of the desktop to theapplication program and reducing the difficulty in presenting theshortcut icon on the desktop.

In the above embodiment of the desktop generation apparatus, theshortcut for the application program may be presented in different ways,and accordingly the shortcut presenting unit 503 has different internalstructures. In the application, preferably the shortcut presenting unit503 includes a message monitoring subunit 5031, a shortcut readingsubunit 5032, an idle block detecting subunit 5033 and a shortcutpresenting subunit 5034. The message monitoring subunit 5031 isconfigured to monitor a message of requiring creating a shortcut for anapplication program on the desktop, which is sent from an operatingsystem of the mobile terminal. The shortcut reading subunit 5032 isconfigured to read a shortcut icon and/or program name of theapplication program for which the shortcut is required to be created onthe desktop. The idle block detecting subunit 5033 is configured todetect an idle block on the desktop. The shortcut presenting subunit5034 is configured to present the shortcut icon and/or program name inan idle block, in the case that it is detected that there is an idleblock on the desktop. Similar to the method embodiment, in the desktopgeneration embodiment, the generated block may be in various shapes, andthe blocks may be arranged on the screen of the mobile terminal inmultiple ways, as long as the blocks can be distributed on the wholescreen of the mobile terminal to form a desktop. In the case that theblock is a rectangular block, multiple (N×M) blocks may be arranged in amatrix, where N is the number of the blocks on the desktop of the mobileterminal in a transverse direction, M is the number of the blocks of themobile terminal in a longitudinal direction, and N and M each arenatural numbers greater than or equal to 2. An interval of a presetdistance may be set between adjacent blocks arranged in the matrix tofacilitate trigger reception and improve user experience.
